✨Computational backend: persist cancellation request

[sanderegg]

What do these changes do?

This PR persists computational job cancellation requests in the DB as a time of the request.
E.g.: when a computational job is marked for cancellation it was only known to the current instance of the director-v2. Therefore if it would restart this information would be lost. This is now fixed.

Driving test: test_handling_cancellation_of_jobs_after_reboot

This might help with #6400
